The Christian life is a joyful life. We need to learn to live in joy by savoring the good moments, and by looking past the difficult moments with trust that good things are coming. So many people do exactly the opposite: they wallow in the sufferings and look past the joys because they are certain difficult times are coming. When people are unhappy, they can try to steal the joy from others, and a good example of this is How the Grinch Stole Christmas.
